%X 基于秩的Mann-Kendall趋势检验法、变差系数等方法，利用1962年至2006年相关数据，对漳河下游的径流量年变化趋势、变化稳定程度进行了分析，研究了漳河下游河道流量的演化规律。在此基础上，结合水库的防洪、兴利、生态目标，建立了多目标水库生态调度模型，对漳河下游的岳城水库实施生态调度，并利用粒子群优化算法对调度模型进行了求解。研究表明：建立的模型可综合考虑水库防洪、供水和生态需求，实现多目标调度。从调度结果可以看出，漳河下游径流量呈十分明显的递减趋势，且年际变化大，岳城水库建库后对漳河下游水文情势影响严重；在丰水年汛期，漳河来水可以满足用水，而平水年份和枯水年的缺水形势比较严峻；除汛期以外的其余时段，即使在丰水年也必须通过水库调度放水，才能提供河道用水，否则将出现干涸  The annual variation trend and variation stability degree of runoff in the downstream of Zhanghe River were analyzed using the Mann-Kendall trend method and coefficient of variation method based on the collected data from 1962 to 2006, which provided the evolution of river flow in the downstream of Zhanghe River. On the basis, a multi-objective ecological regulation model of reservoirs was developed according to the objectives of flood control, water conservancy, and ecological environment. The model was used to perform ecological regulation on the Yuecheng reservoir in the downstream of Zhanghe River using the particle swarm optimization method. The results showed that the model can realize the multi-objective regulation in consideration of the flood control, water supply, and ecological requirements. The regulation results suggested that the runoff in the downstream of Zhanghe River has a significant decreasing trend with a large annual variation, and the Yuecheng reservoir can deeply affect the hydrological conditions in the downstream of Zhanghe River. During the flood season of wet year, Zhanghe River discharge can meet the water demand, while the water scarcity situation was serious in the normal and dry years. In the other time periods except for flood season, water release from reservoir regulation was needed to avoid the occurrence of drying in the river.
